Summary On 07March 1997, the oil tanker IRVING ARCTIC, under the conduct of a pilot, was proceeding in the St.Lawrence River upbound for Trois-Rivires, Quebec. While making a course alteration, the IRVING ARCTIC struck a shoal east of Brisants Sainte-Croix in the Traverse Cap-Sant. Helm manoeuvres were used to bring the vessel back to the middle of the channel. The bottom plating was holed, causing an ingress of water at the forepeak. There was no injury or pollution as a result of this occurrence. Ce rapport est galement disponible en franais. Other Factual Information Particulars of the Vessel History of the Voyage On 06March 1997 at 0402 eastern standard time (EST)[2] in the Port of Qubec, Quebec, two pilots boarded the IRVING ARCTIC to take the tanker to Trois-Rivires, Quebec. As berth No.20 in the Port of Trois-Rivires was not available until the next day, the pilot and ship navigation personnel agreed to drop anchor in the Saint-Nicolas anchorage area. The vessel departed the anchorage area on March 7 at approximately 0510. The first pilot had the conduct of the vessel. At about 0700 there was a watch change, and a new helmsman took over at the steering position. The officer of the watch (OOW) plotted the vessel's position on the chart. The second pilot took over the conduct of the vessel and the first pilot went below to have breakfast in the dining room. The vessel's navigation was by visual and radar observation. The pilot used the parallel index method on the starboard radar while the master and the OOW kept watch on the port radar. The weather was clear, with visibility of 10 nautical miles, and the winds were light. There was fast ice along the banks of the river, and the ice concentration in the channel was estimated at approximately 0.4. The log indicated a ground speed of approximately 10.5knots. On the Saint-Antoine course, the pilot used the radar to measure the distance between the vessel and the north shore and found that the vessel was slightly south of mid-channel. The pilot gave the order to steer 252 gyro (G). Using the Saint-Antoine range as a visual mark aft of the vessel, the pilot observed that further compensation was required and gave the order to steer 254G. When the vessel returned to the middle of the channel, the helmsman was ordered to steer 250G. Off spar buoyQ46, the pilot ordered the helmsman to steer 260G to initiate the alteration from the Saint-Antoine course to the Traverse Cap-Sant. At 0714 the pilot informed the Marine Communications and Traffic Services (MCTS) that the vessel had reached the Sainte-Croix calling-in point. At 0716 the OOW plotted the vessel's position as approximately half a cable northwest of the Sainte-Croix calling-in point. The pilot adjusted the variable range marker of the starboard radar to a range of 2.2 nautical miles. While the pilot maintained a radar watch, it was asserted that the glare of the sun restricted his view of the automatic radar plotting aid. This account of events was not corroborated by the ship's navigation personnel. When the variable range marker was observed to have reached the image of the Donnacona wharf, the pilot ordered the helmsman to steer 270G. When the Hydro-Qubec tower north of the Rivire Jacques-Cartier was in line with the Donnacona escarpment, an order was given to steer 280G. The course alteration was made again as requested, but a check on the radar revealed that the variable range marker did not encompass the shore of Pointe Jacques-Cartier, which led the pilot to believe that the vessel was again south of mid-channel, and at once he ordered a course of 285G. Meanwhile, at 0724, the OOW used the port radar to measure the distance from the vessel to the Donnacona wharf and to the point at Cap-Sant. The position plotted on the chart showed that the vessel was south of mid-channel. Now in the approaches of the Traverse Cap-Sant, the pilot discovered that the object that he was using as a visual mark was not spar buoyQ50, but a piece of ice, and he ordered hard over and pointed to starboard. The OOW, surprised by the helm order, looked toward the Sainte-Croix range aft of the vessel and noticed that the vessel was south of mid-channel. Before the helm reached hard-a-starboard, the pilot ordered 310G. In the following moments, the pilot ordered a series of helm manoeuvres to steady the vessel in the middle of the channel. The master, witnessing these manoeuvres, turned his attention to the echo-sounder plotters, which showed a significant decrease in water depth. Concerned that the vessel had struck bottom, he at once ordered the first mate and the third engineer to sound the compartments. At 0730 the OOW again plotted the vessel's position. The position showed that the vessel had returned to the middle of the channel. At 0805 the first mate advised the navigation team that there was an ingress of water in the forepeak. No other ingress of water was reported in the vessel's lower compartments. The main engine was slowed in anticipation of dropping the anchor. The MCTS were informed of the manoeuvre, and the anchor was let go off Lotbinire, Quebec, at 0822. At 0932 it was noted that the forward draught had increased to 11.13m. The crew transferred cargo aft until the vessel was on an even keel with a draught of 10.67m. At 1018 the tanker departed the anchorage and, at 1704, arrived at berth No.20 in the Port of Trois-Rivires. The strong current in the Port of Trois-Rivires prevented divers from inspecting the hull. On March 10 the vessel anchored at Baie-Comeau, Quebec, and an underwater inspection the next day revealed that the damage was confined to a crack in the bottom plating under the forepeak. On March 7, at approximately 0724, the tide gauge recorders at Neuville and Portneuf indicated water levels of 4.60m and 4.15m above chart datum. Based on the mean water level between the two tide gauges and the tanker's forward draught, the available information suggests that the vessel struck the shoal east of Brisants Sainte-Croix. Passage Planning and Pilotage Bad weather and icing in the channel sometimes unduly prolong a pilotage assignment. In anticipation of an increased workload during the winter season, two pilots are assigned to each vessel. The pilot was not required to submit, and had not submitted, a passage plan to the vessel's personnel. The navigation personnel had not prepared a detailed passage plan which might have shown, among others things, courses to steer, parallel index distances, and wheel-over positions to assist in the navigation. Instead, they relied on the pilot's expertise. The pilot and the vessel's personnel had not shared navigational information, apart from a brief exchange at the beginning of the assignment. In 1995 the Board published A Safety Study of the Operational Relationship Between Ship Masters/Watchkeeping Officers and Marine Pilots (TSB Report No. SM9501), which contained several recommendations regarding Bridge Resource Management (BRM). In particular, the Board recommended that the Department of Transport require that, as part of their initial hand-over briefing, pilots obtain the master's agreement to the intended passage plan, and invite the bridge team's support by having the OOW plot and monitor the vessel's position at regular intervals and report the position to him with respect to the agreed passage plan (TSB Recommendation M95-08). Regarding team work, the Board further recommended that the Department of Transport require that the initial training syllabus for all ship officers be modified to include demonstration of skills in BRM (TSB Recommendation M95-09); and that all ship officers and pilots be required to demonstrate skills in BRM before the issuance of Continued Proficiency Certificates to the former (TSB Recommendation M95-10) or before the issuance or renewal of a pilotage licence to the latter (TSB Recommendation M95-11).
